Attempted to write to read only memory - BEdaisy.sys BSOD crash

Hi, Winters Sin.

Thank you for posting in the Microsoft Community.



From your description, I understand that you received a crash message while playing War Thunder on Windows 11. I understand your confusion about this issue.



Receiving the "Attempted to write to read-only memory - BEdaisy.sys BSOD crash" error is usually related to the system's memory or drivers, especially when there is a problem with the BattleEye security anti-cheat software while running.



Graphics card drivers may cause compatibility issues with BattleEye or the game. Please make sure your graphics card drivers are up to date.

You can visit the official website of your graphics card manufacturer (such as NVIDIA or AMD) to download and install the latest version of the driver.



BattleEye is the anti-cheat system in "War Thunder" and may cause this error due to an incomplete update.

Try to manually update BattleEye:

Go to the game directory and find the BattleEye folder.

Run the Uninstall_BattleEye.bat file in the BattleEye folder.

Then start the game and it will automatically reinstall BattleEye.



Some antivirus software may conflict with BattleEye, causing a blue screen crash. Try disabling the antivirus software temporarily and check if that solves the problem.

Disclaimer: After you try disabling your firewall or antivirus software for testing, immediately turn on your firewall or antivirus software to prevent viruses from posing a threat to your PC.



Besides this, you can also try contacting the game's support for further assistance.

Short answer: no.

Long answer: Your memory sticks are going. Memory sticks don't really do well in high read/write situations because they only have so many read/writes they can do before they bite the dust. So yeah. Use magnetic storage instead.

I have the same issues:

The worst part is TC/Microsoft don't care to fix It, they don't read. Only Nvidia replied me they're already investigating the root cause, but I doubt that.

Installing it on the 4GB will be faster for loading times as the internal memory has a quicker read/write speed than any external memory.

Tried all 3. Still crashes to BSOD. Which on my PC is Green.
